IMPROVYEM ENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 216,389, dated J unel0, 1879 application filed March 22, 1879.

To all 'whom it may concern: Y

Be it known that I, WILLARD M. FULLER, of New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Radiators; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification. v

My invention relates to steam radiators; and it consists in the peculiarconstruction of the same, as will be hereinafter more fully set forth,and pointed out in the claims.

In the annexed drawings, Figurelisafront elevation of my improvedradiator. Fig. 2 is a longitudinal vertical section, Fig. 3a transversevertical section, and Fig. 4 a horizontal section, ofthe same.

A represents the base of the radiator, supported upon legs B B. Thisbase extends along the front and around both sides or ends, but leavingan opening at the back. The base is cast hollow, and has verticalcolumns C C and D D rising from it, said columns being surmounted by ahollow chamber, E.

The outer sides of the end columns G C are preferably made round, whiletheir inner sides, as well as the intermediate columns, D, are

made angular, as shown, to produce an en larged heating-surface.

The various columns extend far enough down to have their lower endslevel with the bottom ofthe base, and said columns are cast hollow toform Steamchambers.

For the purpose of removing the cores after casting the radiator, thereare openings a in the top of the 'chamber E, corresponding to theintermediate columns, D, and similar openings at b, in the bottom of thebase A, corresponding to the side columns G C. These openings are tappedand closed by means of screw-plugs F, as shown. 4

In the sides of the base A are openings Gr G for inlet and exit ofsteam.

The back of the radiator thusconstructed is closed by means of a castplate, H, fitting under the top chamber, E, on shoulders d d upon theside columns G, and the lower end of said plate is formed' with a foot,H', corresponding in configuration with the base A. This plate isfastened by means of bolt's c e, passing into the web between the centercolumns of the body of the radiator.

The plate H, with the body of the radiator, forms an air-chamber, I,open at the bottom, the air entering at the bottom and becoming heatedas it passes upward, and then escapes into the room through a series ofholes, w w, in the upper end of the plate.

The radiator, it will be seen, is thus made in two parts only, one partforming the entire steam-apartment, and the hotair chamber being formedby simply adding and securing the other part. There are no joints tobecome leaky.

All the columns are of course closed at their lower ends, and theirupper ends open into the chamber E.

The steam passes in at one side of the base and out at the other,filling in the meantime y all the hollow parts of the radiator.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. In a steam-radiator, the open-back base A, columns C D, and topchamber, E, all cast in one piece, substantially as and for the purposesherein set forth.

2. The combination of the plate H H with the open-back base A, columns CD, and chamber E, to form a steam-radiator with hot-air chamber I,substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLARD M. FULLER.
